Have you ever wondered what advertising sites track your web browsing? Sheepish is an extension for Chrome that shows you exactly which companies are keeping an eye on you for every site you visit and blocks them from doing so.

Initially, Sheepish doesn't seem like much, but once you start moving around to new websites and seeing how many different places are tracking your every click, it might be a bit of a surprise. You can set Sheepish to block the tracking once your list gets populated or just let the ads continue to do their thing. Not everything that tracks you is always bad, sometimes its as simple as Google Analytics, but if you want a more covert and private browsing experience, Sheepish is worth checking out.

Update: It looks like Sheepish has been pulled from the Chrome Web Store because it was using the codebase of another Chrome extension, Ghostery, we suggest you use Ghostery instead.
